“I used an older Arduino simply because I wanted a quick and dirty 3.3v source for the iphone to arduino serial interface. The perfboard has a tip120 to drive the remote start, all the interface wiring for the car, power supply and the iphone interface.”

Instructables member JetricaKerempuh has posted a step by step approach to build a cool tripod for your iPhone. He feels that without Tripod it’s pretty hard (and frustrating) to take any full figure shots.

For this project, you’ll need just few tools and those are — small screwdriver, measuring tape, pliers, sharp knife, superglue, small awl and iPhone tray.

An instructables member, MattBothell shares his amazing work of constructing an iPod/iPhone Projector that according to him, has good enough quality to enjoy a full length movie from your iPod Touch or iPhone.

With his step-by-step design tutorial you can actually build yourself a projector with just a few cheap objects and ingenuity! The whole project only cost you a dollar. The way it works is the light from your phone or iPod goes through the magnifying glass and magnifies onto the wall. The whole project is very easy to make and easy to understand.
